Figure 1. Operating Features

Initial Set Up

After the machine has been installed and before you use it for the first time:

1.Check that the electrical supply current and voltage that the machine is connected to are the same as stamped on its name plate. For three-phase machines, also check that the direction of rotation is correctly set by the turning knob (Figure 2, F). Refer to the tag attached to all three-phase machines for detailed instructions.

CAUTION

Operating this machine from an incorrect electrical supply may damage it.

2.Check that the machine has been lubricated according to the schedule listed in Routine Maintenance–Lubrica- tion on page 5.

Note: At this time, carry out the full monthly lubrication schedule on page 5.

3.Make sure that the sharpener is in the locked position. To do this, push in the turning knob (Figure 2, F). While depressing the turning knob, turn the machineover a few revolutions by hand to see if the knife reciprocates easily. If the knife does not move easily, the sharpener may be in the unlocked position.

4.To lock the sharpener in place, lift the release lever (Figure 2, D) and press the sharpener lever (Figure 2, E) to release the sharpener. Raise the sharpener bracket (Figure 2, S) by hand to lock it in place. Once the sharpener is locked in place, you may disengage the release lever and sharpener lever. Repeat step 3 to ensure that the sharpener is now locked. If not, repeat this step.

5.Visually inspect the blade to ensure that the top of the knife is flush with the knife lockbolt (Figure 7, 1 on page 9) and that the knife is perpendicular to the baseplate. If you need to adjust the alignment of the blade, see section Changing the Knife on page 9.

6.Check that the motor switch is in the OFF position. Then connect the attachment plug to the terminal block on the machine.

7.Hold the operating handle and turn on the machine. Allow the blade to reach full speed. If the blade is struggling, the sharpener is still not in the locked position. If this is the case, turn off the machine and do the following:

7.1 With your left hand, straddle the front of the sharpener with fingers and thumb.

7.2 Press the bell crank release lever (Figure 2, H) to disengage the sharpener mechanism from the motor.

9.Re-engage the back guide (Figure 6, 6) in loose contact with the back of the standard.

Checking the Sharpener Shoes

The shoes should swing in and out freely without excessive up and down play. If adjustment is necessary, proceed as follows:

1.Loosen the locknuts (Figure 6, 3) and tighten the screws (Figure 6, 7) as required.

2.Check the clamping arm (Figure 6, 10) with the belt carrier in the most downward position and the knife in the most upward position. The clamping arm should keep the sharpener shoe from moving in. If it fails to do so, the serrations on the clamping arm are worn or the sharpener shoe (Figure 6, 11) is worn.

3.Replace worn part(s) as necessary.

Checking the Extreme Down Position of the Sharpener

The correct down position is with the tip of the knife at the center of the belt on the shoe (Figure 6, 12). The belt should be in the most downward position, and the knife should be in the most upward position. If the belts are too high, the bottom point of the knife will not sharpen. If the belts are too low, the bottom point of the knife will round off excessively. If adjustment is necessary:

1.Raise the belt carrier to the up position.

2.Remove the plastic cap from the tube for the screw shaft.

3.Insert a pin through the hole in the tube (Figure 6, 13) to prevent the spacer (Figure 6, 14) from turning. Then remove the locknut (Figure 6, 15).

The following step describes the correct procedure for setting spacer adjustment on different stroke machines:

Note: Prior to beginning adjustment, be sure that the spacer is threaded fully onto screw shaft.

Stroke	Turns
1-1/8"	11
1-1/4"	9
1-1/2"	13
1-3/4"	8

Note: Each turn = 1/32"

4.Turn the spacer clockwise with wrench C6153 to raise the bottom position, or turn counter-clockwise to lower the position.

Note: One turn in either direction adjusts the position by 1/32".
